研究结论：(1)基于管线相对地铁结构的竖直距离和相对水平距离，将管线与地铁的邻近等级划分为I-V五级；(2)地下管线安全控制标准应以管线垂直和水平变形作为控制标准更具代表性；(3)提出基于管线变形、管线用途、管线运行状况，将地铁施工诱发临近管线安全风险划分为安全、基本安全、危险、比较危险、很危险五个等级，根据不同安全风险等级在施工前或施工中采取针对性的地下管线保护措施；(4)通过武汉某隧道竖井基坑工程进行实际应用，达到较好效果；(5)研究成果应用领域为隧道工程施工安全管理。

Research conclusions: (1)According to the horizontal and vertical relative distances between the metro structure and the adjacent pipeline，the neighboring grade is divided into five levels(I-V); (2)To use the horizontal and vertical pipeline deformations as indicators to establish the safety control standard for the underground buried pipelines is more representative than other indicators; (3)With the deformation of the existing pipeline, usage, and its operation status taken into account, the safety risk of the tunnel-induced pipeline damage can be assessed into five different levels, namely Safe, Basic Safe, Dangerous, Basic Dangerous, and Very Dangerous. Corresponding prevention and protection measures are further proposed before and during the construction process for the adjacent pipelines according to their evaluated risk levels; (4) The proposed method is applied in one shaft foundation pit excavation project in Wuhan metro tunnel construction, and the results demonstrate the feasibility of the proposed method; (5)The research conclusions can be used in the metro tunnel construction fields by providing decision supports on the construction safety management.
